domestic water well Applications

  • Constant Pressure pump control valves

    For use with water well pumps and booster pumps, the Cycle Stop Valve (CSV) turns any pump into a variable flow, constant pressure system. Working in conjunction with a small pressure tank, the CSV is usually adjusted to the middle of the pressure switch range. IE; 40/60 PSI switch, 50 PSI CSV. The size of the pressure tank determines how much water can be used by the house, before the pressure drops to 40 PSI, and the pressure switch starts the pump. As long as flow rates in and around the house vary from 1 GPM to as much as the pump can produce, the CSV maintains a constant 50 PSI on the system. When there is no more flow required for the house, the CSV allows the little pressure tank to fill to 60 PSI, and the pump is shut off by the pressure switch.

  • Water treatment systems for chemical industry

    The effluents that accrue in the cleaning process of silo vehicles and containers for transportation of raw materials for the chemical industry, are highly complex and constantly changing in the composition of wastewater. Flocculation as the prior art of treatment for chemical waste water can not remove many of the completely dissolved invisible substances. Thus, the residual stresses are evident despite high claritv of the `Treated effluent` is often well above the levels witch are applicable for wastewater in domestic environments.

    Grease removing in wastewater pipes

    Whether a collection system is handling domestic, commercial, or industrial waste; grease accumulation causes problems in wet wells, lift stations and pipelines. Problems with grease include interference with wet well level controls, reduced wet well capacity, plugging of pipes and pumps, and unsafe working conditions.

  • RDF

    RDF (Refuse Derived Fuel) is made from domestic waste which includes biodegradable material as well as plastics, and has a lower calorific value than SRF (Solid Recovered Fuel). RDF (Refuse Derived Fuel) is used in combined heat and power facilities, many of them in Europe where they produce electricity and hot water for communal heating systems in the local area. Compared to landfilling, the lower carbon emissions resulting from RDF manufacture outweigh the emissions associated with transporting the reclaimed fuel. The increasing importance of Waste to Energy/RDF Waste to energy conversion is an increasingly recognised approach to resolving two issues: waste management and sustainable energy. Waste represents an increasingly important fuel source. Using waste as fuel can have important environmental benefits. It can not only provide a safe and cost-effective way of waste disposal but can also help reduce carbon dioxide emissions.
