Reverse osmosis used for surface water treatment

We supply a range of Visible Sheet Polariser for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers within Consumer Electronics. Our Linear Polarisers linearly polarise unpolarised light and can block light that is polarised in the opposite direction. Linear Polarisers are often used in the production of LCD monitor and TVs. The liquid crystals act like a wave-plate, rotating the polarisation axis allowing them to control the amount of light from each pixel. They are used in a similar way for a photographer to prevent surface reflections from water. Our polariser sheets allow different levels of total light from a randomly Read PDF for more information...

The surface net with flat net is ideal for sampling and collecting solids and organisms from the water surface. The sampler is particularly suitable for taking samples from basins, tanks, shafts, open waters, etc. Sample depths of up to 6 m can be reached with the length-adjustable aluminium telescopic rods. The TeleSchöpfer telescopic rod with tools is a versatile sampling system. The interchangeable tools (angle cup, pendulum cup, bottle holder, stainless steel cup and landing net) are suitable for a wide range of applications. The tools are firmly connected to the telescopic rod by a practical snap connection.

Waste water treatment plants and surface waters have enormous energy potential. A sewage treatment plant, for example with 90 million litres of wastewater daily, reducing the wastewater temperature by using heat exchanger by around 1°C, generates a power of about 4.3 MW. The comparative potential for energy recovery from the surface water is even higher. Environmental aspect Induced by humans, water temperatures of the surface and streams have steadily increased, not least owing to the inflows from sewage water treatment. This has serious consequences on the flora and fauna. If heat is extracted from purified water in the sewage treatment plant or from surface waters and from streams, and water temperature is thereby reduced, this will have a positive effect on the entire ecological system. With KASAG heat exchanger systems, on the one hand, the energy requirement of the sewage treatment plant can be covered and, on the other, buildings in near vicinity can be heated or cooled.

The central idea of high pressure tools is to concentrate the energy of a high pressure water jet at the smallest possible point to maximise its effect. The smaller the area to be sprayed, the slower the process will be on large areas. The solution is to move the high pressure water jet quickly and systematically. Rotating joints allow the water to be transferred from fixed to rotating parts of the high pressure tool so that the water jet is moved in a targeted manner. KAMAT rotary joints are suitable for pressures up to 4,000 bar. They can be driven by internal or external energy and can reach up to 3,000 revolutions per minute. For fatigue-free and safe working, we also offer easy-to-use swivels for high pressure hoses, suitable for our high pressure pumps. Also designed and manufactured in-house, these swivels are internally streamlined to minimise flow restrictions.
