'back washing'

Grech CPA15000 Auto Cleaning Pressurized Koi Pond Filters (15000 L/H) New pond filter generation: Bio pressure pond filter CPA-15000 Characteristics: Indicator for pollution High flow rate Optimum development of biological pond filter Easy and uncomplicated bio-pressure pond filter-system This system provides fast and reliably clear water Easy backwashing (by flipping a switch) Different filter materials (special filter foams) Advantages: Mechanical and biological pressure filter with integrated UVC-clarifier. All connections and technology are in the lid/cover, the filter can be buried to lid for concealment without difficulty. Flush back function with maintenance indicator. Cleaning and maintenance: The water can be pumped to a higher lying waterfall and then led back into the pond. The annual maintenance is limited to checking the filter media and the UV-lamp. The filter has a modern flush back function that can be adjusted by means of a switch with four functions. With the switch you have the following possibilities for setting: The EasyClean flush back function: • Switch position "Filter" Normal operation - the water passes through the pressure pond filter with the help of a pond pump and returns cleanly into the pond. • Switch position "Clean" Cleaning mode - By turning the switch the motor that is integrated in the top of the filter is switched on and makes the filter sponges rotate in the inner of the pond filter and cleans them from the coarse dirt without opening the pond filter. During the cleaning operation the dirty water is drained by an additional connection and can be used for example for garden irrigation. Filter Placement: The filter is placed at the pond side and by means of a a suitable pump (not included in delivery) connected with the water. The water circulates through the filter and the UV-device and after being cleaned is led again into the pond. Fundamental Functionality: Pond filter combine the mechanical and biological cleaning. Microorganisms settle on the filter material and remove germs and bacteria from the water. By mechanical filtering, suspended particles and dirt remain in the pond filter and by this means no longer return to the pond water. It takes about 4-6 weeks, until Filter Bacteria have sufficiently colonized the bio pond filter. Only thereafter t is advisable to switch on a UVC Pond Clarifier. Starter bacteria help to shorten the start-up phase of a new filter. Starter bacteria refer to microorganisms especially grown in a laboratory. By adding them, you can shorten the start-up phase considerably. Bacteria are active above a temperature of approximately 10°-12°C, the pond filter´s temperature should exceed 40°C. So the pond filter should be placed in the shadow and not be exposed to direct sunlight. UVC-pond clarifiers irradiate the water in a flow-through reactor with UV rays. The UV-C radiation destroys the swimming algae. The algae agglutinate to large particles and ca be easily removed by means of mechanical filtering. Our UVC clarifiers modify the tertiary and the quaternary structure of the algae proteins by means of UV-radiation. This means the destructions of the algae which can be removed from the water by pond filters.

A three-tier fountain nozzle is a type of fountain nozzle that produces a cascading water effect in three distinct tiers or levels. It creates an aesthetically pleasing water display where water flows from one tier to another, creating a visually appealing and soothing effect. The three-tier fountain nozzle achieves its effect through a combination of water pressure and carefully designed nozzle openings. Here's a general explanation of how it works: Water Supply: The fountain is connected to a water supply system, such as a pump or a pressurized water source, which provides the necessary water pressure to operate the fountain. Nozzle Design: The three-tier fountain nozzle is specifically designed with multiple levels or tiers. It typically consists of a central nozzle surrounded by outer tiers or rings. Each tier has its own set of nozzle openings. Water Pressure: The water pressure from the water supply system is directed through the nozzle openings. The pressure propels the water out of the nozzles and into the air, creating a continuous flow. Cascading Effect: The design of the nozzle openings on each tier determines the shape and direction of the water streams. As the water shoots out of the nozzles, it forms distinct arcs or jets that fall gracefully from one tier to the next. Water Recycling: Typically, the water that falls from the upper tiers is collected in a basin or reservoir at the base of the fountain. From there, it is recirculated back to the water supply system through a pump, creating a continuous cycle. The specific design and configuration of the three-tier fountain nozzle may vary depending on the manufacturer and the desired effect. Some fountains may also incorporate lighting effects or adjustable water flow to further enhance the visual appeal. Overall, the three-tier fountain nozzle achieves its stunning effect by combining water pressure, carefully designed nozzle openings, and a cascading water flow, resulting in a beautiful and captivating display of moving water.

Umbrella jet fountain nozzles are commonly used in decorative water features, such as fountains, pond or pool displays, and water gardens. They are designed to create a visually stunning water spray in the shape of an umbrella, which can add to the aesthetic appeal of a water feature. Umbrella jet fountain nozzles can be used in both residential and commercial settings, and are popular in parks, public spaces, and private backyards. They are typically used for their aesthetic value and can enhance the overall beauty and tranquility of any water feature.

Foam jet nozzle This stainless steel foaming jet nozzle produces a 1" thick jet of gushing foam effect water. Not only attractive but great for oxygenating your pond. The lively bubbling water pattern generated by the foam effect nozzles is the optimal accessory for watercourse inlets, stepped pool installations, or fountain installations. By mixing air with water, the pattern appears to be extremely high-volume. Nevertheless the nozzles actually have a low water requirement. The beautiful soft foam jet offers a strong contrast to the background pond and landscape. As opposed to Cascade and Geyser nozzles, Schaumsprudler foaming jet nozzles work independently of the water level so that fluctuations in the water level do not affect the water pattern. Foaming Jet Nozzle characteristics at a glance High-contrast, lively water pattern Foam / spume effect Trouble-free continuous operation Offers oxygen enrichment Extensively wind-stable Water-level independent

Bubbling Foam Nozzles This stainless steel foaming jet nozzle produces a 1" thick jet of gushing foam effect water. Not only attractive but great for oxygenating your pond. The same nozzle is used with different size pumps to achieve different jet spray heights.

Diamond jet nozzle also know as Palm tree fountain nozzle It is a Simple nozzle made up of a set of 4mm jets arranged in such a way that on their ascent they simulate the trunk of a palm tree and on its fall its leaves. The inclination given to the water jets makes the viewer see from their position the intersections of the front with the rear causing an effect of great aesthetic beauty in the ornamental fountain. The range is made up of three sizes in 1", 1½" and 2½". The angel given to the jets means that, from wherever they are positioned, spectators can see the front & back jet cross over producing an aesthetic effect of great beauty in the architectural fountain. The range is comprised of three sizes with 15, 20 & 30 fountain jets. Construction shall be cast bronze with precision clear stream brass nozzle neoprene gasket and stainless steel fasteners.

Stainless Steel Waterfalls are a simple solution to creating a waterfall or water shoot in your garden. Made from high quality stainless steel they allow a single hose to supply water which is then internally baffled to create an even sheet of water. To increase the ease of installation these waterfalls have a connection at the bottom, so one can be fitted with a connection hose tail. We suggest the largest size pipe that your pump can accept should be used. As with all waterfalls the flowrate required to ensure that the sheet is still wide enough when it hits the surface of the pond / reservoir is determined by both the width of waterfall and the installation height. Stainless Steel Waterfalls Features • High quality 304 grade stainless steel • Single hose connection. • Back or bottom connection position • 50mm deep lip • Can be wall mounted • 2 year guarantee
