Surge Tanks for Water & Wastewater Systems from Charlatte

Charlatte is the world leader in the design of bladder-type pressure vessels used in potable, raw and wastewater applications. Charlatte tanks are used in a wide range of applications such as surge protection, pressure regulation, pump cycle control, pressurized storage and chlorine contact.

Harper Control Solutions represents, sells and services Charlatte tanks for Potable Water and Waste Water systems.

Potable Water Systems

Charlatte’s HYDROCHOC surge protection vessel is designed for water hammer and surge protection on clear water, and potable/drinking water systems.

The HYDROFORT is available in vertical and horizontal designs and has a bladder that is fixed to the outlet/inlet connection located on the bottom or side of the vessel. The bladder is attached to the inside top of the vessel, so it can expand to the full size of the vessel. This allows for greater drawdown volumes, and less stress on the bladder. The air is trapped in the space between the outside of the bladder and the wall of the vessel. Therefore the liquid is not in contact with the steel walls of the vessel.

The HYDROCHOC vessel is available in a range of 25 to 40,000 gallons, and service pressures of 50 to 1160 PSI.

Wastewater Systems

Charlatte’s ARAA vessel is a self regulating surge vessel used for raw water, wastewater and sewage that works without any bladder or air compressor unit..

Restrictions apply to the use of the ARAA vessel. It has to be replenished with atmospheric air every 24 hours. The pumps have to be stopped at least once a day for the ARAA to recharge naturally with atmospheric air.

The ARAA has a central tube and a two way air valve made special for wastewater.

In comparison to a conventional hydropneumatic vessel, the AARA needs neither a bladder nor an air compressor or related accessories; therefore there is no risk of abrasion or piercing. The reliability is greatly improved and the maintenance is reduced even further.

The AARA vessel is available in a range of 25 – 26,000 gallons, and service pressures up to 125 PSI.

Charlatte’s EUV surge protection vessel is designed for raw water and wastewater.

The air is in the bladder, which is fixed to the top of the vertical vessel only. This causes no obstruction to the inlet/outlet orifice. The rubber bladder has a heavy duty protective coating to resist aggressive water and sharp objects.

The EUV has a flanged connection pipe with an extrusion grill that keeps large objects from entering the tank.

These vessels are treated internally with ENDOKOTE epoxy paint for corrosion protection. The EUV vessel is available in a range of 25 to 18,500 gallons, and service pressures up to 400 PSI.
