Municipal Waste Water Applications

VACOM SYSTEMS™

Municipal Waste Activated Sludge (WAS)

Water supply and water quality degradation are global concerns that will intensify with increasing water demand, the unexpected impacts of extreme events, and climate change. For this reason, marginal-quality water will become an increasingly important component of agricultural water supplies, particularly in water-scarce countries and arid areas such as the US Inter- Mountain West.

Effluent Recycling

Approximately, seventy (70) percent of world water use including all water diverted from rivers and pumped from underground sources is used for agricultural irrigation. The reuse of treated municipal wastewater for purposes such as agricultural and landscape irrigation reduces the amount of water that needs to be extracted from natural water sources as well as reducing discharge to the environment. Thus, treated municipal wastewater is a valuable water source for recycling.

Water recycling is reusing treated wastewater for beneficial purposes such as agricultural and landscape irrigation, industrial processes, toilet flushing, and replenishing a ground water basin (also referred to as ground water recharge).

Vacom is working with a major international engineering firm to recover additional water from reverse osmosis (RO) reject used to treat and recover water from wastewater treatment effluent.

The recovered water from RO and from a Vacom evaporator/crystallizer will be used for ground water recharge in the US Inter-Mountain West. The Vacom system acts a final process to limit concentrated brine discharges by converting the brine to a solid waste thereby eliminating the possibility that a brine stream can redissolve into a usable water source.

As projects like these become accepted as the norm rather than the exception, drought conditions can be substantially alleviated.

Digester Enhancement

Municipal sludge management and digester enhancement will be discussed in its own market segment utilizing the Vacom Flash Hydrolyzer™.

The Vacom Flash Hydrolyzer™ economically ruptures and denatures single cell bacteria in the sludge allowing for complete pathogen destruction at our boiling operating temperatures. Additionally, the Hydrolyzed sludge yields approximately 25% greater Renewable Natural Gas (RNG) recovery in anaerobic digesters and greatly enhances the mechanical “dewaterability” of the final sludge and/or digestate.
