Water Process & Fluid Treatment

The Robot 90 sludge extractor consists of a suction nozzle on an articulated pipe arm, which extends from a vertical stand fixed in a suitable place of the sedimentation basin. The nozzle and the pipe are connected to an external pump and the sludge is sucked up from the basin’s bottom to an external container for further treatment, such as thickening or dewatering.

Johnson Screens offers 16 unique power frames for reverse osmosis (RO) service.

Each has been carefully designed and tested for optimal performance in the most demanding RO applications. Our standard materials of construction are well-suited for all ranges of operating conditions; however, we also provide specially engineered construction or materials upon request.

For various applications, we offer bare pumps and simple pump packages, as well as complex pumping systems.

Johnson Screens^® screen compactor is an integrated machine consisting of a screen, a shaftless spiral and a press unit. During operation, solids within the incoming flow will progressively collect onto the screen surface and cause it to gradually blind. The upstream water level will rise and at a predetermined level the spiral will be activated.

Ion removal technologies present operators minimized efforts, easily managed waste stream, with minimal water and sand environmental impacts. There is no high strength liquid waste stream with environmentally benign solids and essentially damp sand. There are also potential solids reuse opportunities with this process.

 The first step in minimizing downstream water treatment costs is to obtain and maintain a reliable and best quality water source. Whether that source is surface water or ground water, Johnson Screens has the most efficient, cost effective and environmentally responsive solutions for the elimination of undesirable matter through primary, secondary and tertiary screening solutions.

Johnson Screens’ teams of experienced welder fabricators are available for on-site installation, repairs and screen replacement. Our team can evaluate the condition of screens and make recommendations as to the best course of action to allow the screens to operate at maximum capacity.

The first step in wastewater treatment is normally the removal of solids from the wastewater flow by means of screens. The removed screenings contain household waste, faecal matter, toilet paper and mineral solids.

The screenings volume depends, not only on the separation size of the screen, but also on the type of sewer system. Johnson Screens has a number of products that will suit your screening needs.

The BTU/in-line self-cleaning filter is a continuous-operation pressure filter. Heavy duty compact filters with a robust housing are designed to deliver an uninterrupted flow through stainless steel Vee-Wire®.
