Nozzles

Wedge wire nozzles prevent the outflow of filter media, activated carbon or sand and secure an even distribution of water at the same time.

Advantages

• Long lifetime: when regeneration of active carbon is done at high temperature, plastic becomes brittle. Stainless Steel Nozzles are excellent solution.

• Made to customer specifications

• Strong construction

• No clogging due to triangular slot

Distributor / Collector (Laterals)

Ion exchange unit and multimedia filters are often equipped with a distributor/collector. BTOSLOT has extensive experience and expertise in designing the collector system for your needs. We can distinguish 2 types: a horizontal header with lateral connections or a central hub, installed vertically in the vessel with radial connections. The latter is ususlly used in smaller vessels. If you wish we can foresee a support construction or braces.

Technical details

• Materials: 316L, Duplex, Super Duplex

• Slot opening: 0.05-0.5 mm

• Pipe based laterals to ensure a perfect distribution

• Connection to header/hub can be either through threaded fitting or flange

Advantages

• Superb backwash ability and non-clogging

• Custom-made

• Excellent flow distribution

• Strong construction

• Low maintenance costs

Resin Traps and Strainers

A resin trap or strainers serves to retain particles in a process flow. The quantity of the particles is in general very low to so that cleaning can be done during flow interruption.

A resin trap is normally used to capture expensive resin that escapes from a treatment vessel by accident or to protect equipment further downstream.

A strainer is often used in tubes to block unwanted particles or dirt that would otherwise damage downstream equipment. Cleaning is carried out by removing the strainer from the tube.

Filter Cartridges for Automatic Backwash

During the filter cycle the solids are deposited on the smooth surface of the filter element. A “cake” is built up and acts as an extra filter for the finer particles. The fines that slip through, do not become lodged within the conical slots. By reversing the flow, the cake and dirt are removed from the filter surface. This is the backwash cycle. The most common flow used for the filter cycle is in to out.

Technical details

• Materials: 316L, Duplex, Super Duplex, SMO254, Hastelloy, Monel400

• Construction: radial external wire / axial internal wire

• Slot: 0.025mm and above

• Diameter: 25mm and above

Advantages

• Wedge wire is No. 1 when it comes down to cleanability

• Mechanical strength

• No clogging

• No maintenance or replacement costs

Slot Tube for Self Cleaning Filter

A slot tube where the slot runs in the axial direction, with smooth surface on the inside can be cleaned by a suction plate, a scraper or by bernoulli effect.

Technical Details

• Construction: axial internal wire FITO

• Slot: 0.015mm and above

• Diameter: 25 mm and above

Cylindrical Intake Screens

While coanda screens are installed just beneath the water surface, cylindrical intake screens are fully submerged. They retain larger particles and water life floating in the river and protect pumps and installations further up the production line. The controlled lower slot velocity along the screen surface also reduces the likelihood of impingement and entrainment of marine life.

This type of intake screen also has the ability to be cleaned using an air backwash system whereby a controlled burst of compressed air is deployed.
