Water and Wastewater

Accurate measurements are paramount for effective water and wastewater treatment. With fixed and portable monitors, plant operators can keep everything under control and flowing freely for 24/7 operation. Technology is provided for measurement in every water and wastewater scenario - from inlet and primary settlement, through to effluent discharge and sludge treatment for precise process management.

Water and Wastewater

Wastewater inlet is the first opportunity for a site operator to measure and understand the condition of the influent to their treatment process. Measurement at this stage will allow a range of process control actions, ranging from dosing control, through automatic changes to activated sludge processes and diversion of the flow to a holding or storm tank or simply alerting site technicians and supervisors.

The Primary Settlement  or sedimentation tanks are designed to reduce the velocity of the wastewater flow, allowing heavier organic solids (called raw sludge) to settle. They are the first stage of treatment after the removal of rags and grit in the inlet works. Scrapers present in the tank move continuously along the floor of the tank to deposit the raw sludge in hoppers for removal. The scum which floats to the surface is directed by water jets or scum boards to the sludge sump. The raw, settled sludge is removed by pump or gravity feed to a sludge treatment process.

The Activated Sludge Plant is the heart of most recently built treatment plants for municipal sewage treatment and many industrial effluent plants. The activated sludge plant must maintain a careful balance between the biologically active ‘bugs’, the amount of dissolved oxygen, and the load or suspended solids. The use of instrumentation is vital to optimising this process. The ASP process involves the addition of air (oxygen) this is the most energy hungry part of the sewage treatment process and therefore benefits the most from our accurate and reliable measurement devices. See more here

Measurements made at the intake point to a drinking water treatment plant can prevent damage to the treatment system and reduce treatment costs. Our WaterWatch² range provides measurement of colour, pH, oil on water and turbidity, all of which can provide information that is vital to the control process.
