The Buschjost 82400 Solenoid operated diaphragm valve has been specially designed to handle water in the treatment process of wastewater. In this article, we explain why these versatile valves are ideal for chemical dosing applications.

Solenoid valves for wastewater treatment

Water is one of the most valuable resources on Earth and individuals and companies alike are becoming more responsible about the effective treatment and recycling of wastewater. In commercial applications, wastewater is treated and recycled for fertilisation, irrigation and biogas applications.

The Buschjost brass, stainless steel and plastic diaphragm valves are developed specifically for handling water and are ideal for controlling both the intake and treatment process of wastewater. The application story below gives a real-life example of where the Buschjost range of diaphragm valves have added value to water applications in a real-life setting.

Solenoid valve for sewage treatment

Sewage treatment is the process of removing contaminants from wastewater and household sewage. This is done by a physical, chemical, and biological process to remove the contaminants. The objective is to produce an environmentally safe fluid waste stream or treated effluent and a solid waste or treated sludge. The latter is often suitable for disposal or reuse, usually as farm fertiliser.

Sewage treatment generally involves three stages. The first stage consists of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil, grease and lighter solids float to the surface. In the second stage, the settled and floating materials are removed and the remaining liquid may be discharged or subjected to a second stage.

This second stage is where the removal of dissolved and suspended biological matter takes place and is typically created by indigenous, water-borne micro-organisms in a managed habitat. The third stage is where the treated water is sometimes disinfected chemically in a process called dosing, prior to discharge into a stream or river.

The Buschjost 82400 range of solenoid valves are ideally suited to chemical dosing applications. In its normally closed configuration with brass body and high flow rates, this valve presents a very cost effective solution. For the handling of more aggressive chemicals, the valve is available with a range of body materials such as stainless steel or polymers whilst the seating materials can be provided in PTFE graphite or EPDM.
