Existing wastewater treatment systems can remove most phosphorus. The harder problem is reliably removing the last fraction needed to meet increasingly tight discharge limits. Last week, Rayna Newkirk and I attended WEFTEC and spent time talking with engineers, equipment suppliers, treatment plant operators and technology companies about phosphorus removal. One opportunity kept coming up: phosphate polishing. Many wastewater treatment plants already have effective biological,

Phosphorus is essential to agriculture, but in wastewater it can become a costly compliance problem. Most treatment plants already remove a large portion of phosphorus through biological treatment. The challenge comes at the end of the process, when operators need to consistently reach much lower discharge limits. That is where regenerative phosphate capture can fit. For a 1 million gallon per day treatment system, Coralyte can be installed downstream of anaerobic treatment,

Cooling towers are essential to industrial operations, but managing blowdown water can become a persistent compliance challenge. As water cycles through a cooling system, dissolved constituents become concentrated. Depending on the makeup water and treatment program, cooling tower blowdown can contain elevated levels of phosphorus, zinc, copper, iron, and other dissolved metals. Traditional treatment can require chemical addition, precipitation, clarification, sludge handling

Solvent extraction and electrowinning (SX-EW) is one of the great success stories of modern hydrometallurgy, responsible for roughly 2.2 million tonnes of high-quality copper cathode in a single year and decades of continuous innovation [2]. The process itself is elegant: a counter-current, multi-stage contacting operation that uses kerosene-based organic solvents and sulfuric acid to concentrate and purify copper before it is won on a cathode [4]. In the tank house, a 175–18

A simple barrel or IBC tote can turn recurring hauling expense into an on-site treatment solution with immediate application and a typical payback of about six months. Two compact deployment options: a replaceable 55-gallon barrel or a higher-capacity IBC tote. THE BUSINESS CASE | Deploy quickly. Remove oil sheen. Reduce or eliminate routine water-hauling costs. Target payback: about six months in typical applications. Why haul water you can treat on site? Stormwater collec

Fats, oils, and grease—commonly known as FOG—can create expensive problems for industrial facilities. Even when wastewater appears clean, free or emulsified oils may remain in the water stream, contributing to discharge violations, surcharges, clogged infrastructure, and disruptions to downstream treatment. Achieving compliance, however, does not always require a large, complicated treatment plant. Coralyte™ Oils media offers a practical alternative: treat oily wastewater by

Stormwater collected in secondary containment areas often picks up oil, fuel, suspended solids, metals, and other contaminants. Even a light oil sheen can prevent the water from being discharged. The result is expensive. Facilities may need to hire vacuum trucks, haul the water off site, pay disposal fees, and clean the containment area before the next storm. These costs can build quickly across multiple locations. Coral Innovations offers a simpler approach: remove the oil o

Bilge water and oily surface water can create persistent problems for marinas, ports, docks, and boatyards. Even small amounts of fuel, hydraulic oil, lubricants, and other light hydrocarbons can spread quickly across the water surface. Cleanup often becomes difficult, labor-intensive, and expensive. Coral Innovations offers a portable treatment approach built around Coralyte Oils media. The system can be deployed where the problem occurs, operated with simple equipment, and

Industrial wastewater compliance does not always require a large capital project. Many facilities face discharge challenges from specific contaminants such as oils, metals, phosphates, or other process-related residuals. These issues often show up in rinse water, washdown water, process water, sump discharge, or polishing streams before final discharge. For many industrial sites, the challenge is not total plant treatment. It is targeted contaminant removal at the right point

Oil spill response has always depended on speed, containment, and absorption. For decades, the standard approach has been simple: deploy absorbent booms, pads, or mats, let them soak up oil, then collect and dispose of the saturated material. That approach works, but it comes with a major drawback. Most conventional oil sorbents are single-use products. They absorb oil once. They become oily waste. They must be removed, hauled, replaced, and disposed of. In recurring oil spil
