Small Space Sludge Management

Central America’s largest poultry producer, DIP-CMI, faced new requirements to meet stricter wastewater discharge regulations with an outdated treatment system. The facility, located in San Jose, Costa Rica, processes more than 100,000 birds per day and prepares them for distribution to local markets. Maintaining legal compliance for discharging the effluent into the local waterway was not only important for continuing operations, but also a fundamental part of the plant’s environmental plan, which safeguards the local population the plant serves.

Grinding Away Clogs

Rags, wipes and other non-flushable products are causing massive clogs in pumps around the country. 

Clogged pumps in wastewater systems are every operator’s worry, holding up operations and requiring a messy and disruptive maintenance call to clear the clog. All types of locations—from municipal collections and private lift stations to small ejector pumps and large pump stations—can be plagued by clogs.

Protecting PC Pumps in Spanish Biogas Plant

Anaerobic digestion offers an efficient, cost-effective process for green energy development while also providing a sustainable solution for the disposal of animal byproducts. In a typical biogas processing operation, manure, wastewater solids, agricultural residues and food scraps are delivered to a digester system. The process uses microbes to break down the organic material through a fermentation process under controlled conditions, resulting in clean biogas and digested material. That digested material is then used to make fertilizer, compost, soil amendments or animal bedding.

Pump Maintenance Eliminated at Apartment Complex Lift Station

Approaching something the same way repeatedly rarely yields different results. Often, it is the consideration of a different perspective that enables ideal solutions. Such is the case at Villa Mountain Vista North Las Vegas – a 400-unit apartment complex with an onsite lift station equipped with stainless steel-bladed pumps to transport influent. While the pumping of sewage out to the municipal collections system should be fairly standard, frequent pump malfunctions were causes for concern.

Adaptable Thickening

When designing a sludge thickening system, there are many considerations to account for, polymer chemistry being chief among them. The right polymer chemistry contributes to more effective thickening at a lower cost. However, the right chemistry also must be complemented by mechanical processes that enable the chemistry to work effectively.
