Boiler feed water The so called „Boiler feed water“ is stored in a feed water tank and continuously feeded to the boiler of a steam generator. A big quantity of feed water is needed for example in steam power plants. The boiler generates steam, which is used for heating, for chemical processes or for driving a steam turbine respectively a steam engine. The feed water is purified in a way, that all harmfull components for the boiler are removed or neutralized. Leakages and evaporation loss are compensated by additional water which is purified in the same way than boiler feed water. Very often, valuable well and potable water resources are used for the generation of process water. Environmental regulations restrict this usage of well and potable water continuously and increase the costs for this resources steadily. The conditioning of stream water to boiler feed water helps saving potable water and means cost advantages. The process of conditioning is based on ultra filtration with down

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...

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 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.
