Sodium batteries are an emerging category of new-energy power sources. Their production process generates alkaline wastewater that requires efficient solid–liquid separation to meet discharge or reuse standards. This document outlines a complete sedimentation and filtration system designed for treating sodium battery manufacturing wastewater, with a treatment capacity of 10 m³/h.

Coalbed methane (CBM) produced water typically contains high concentrations of hardness ions, primarily calcium (Ca²⁺) and magnesium (Mg²⁺). If left untreated, this hard water can cause severe scaling issues in downstream equipment, pipelines, and disposal systems. This article presents a technical overview of a skid-mounted lamella clarifier-based softening system designed for CBM produced water treatment, focusing on the process flow, equipment configuration, and operational principles.

Vegetable peels from a restaurant kitchen. Grass clippings from a park. Fallen leaves from a community garden. For decades, most of this organic waste has ended up in landfills, creating odors, methane emissions, and rising disposal costs.

As global urbanization and industrialization continue to accelerate, the generation of organic waste has reached unprecedented levels. Kitchen waste, food waste, fruit and vegetable waste, agricultural residues, and organic sludge present significant environmental challenges when disposed of through landfilling or incineration. These conventional disposal methods contribute to greenhouse gas emissions, unpleasant odors, groundwater contamination, and the loss of valuable organic resources.

The Activated Sludge Process (ASP) is one of the most widely used biological wastewater treatment technologies in municipal and industrial wastewater treatment plants worldwide.

Selecting the right clarification technology is one of the most consequential decisions in any wastewater treatment project. Two of the most widely deployed solutions are Dissolved Air Flotation (DAF) and Lamella Clarifiers. Both are engineered to remove suspended solids from wastewater,  but they operate on fundamentally different principles and are best suited to different applications.

Brewer’s spent grain (BSG) is the largest byproduct of beer production, accounting for approximately 85% of total brewing residues. With global annual output reaching 39 million metric tons, this fibrous material—composed of husks, seed coats, and undissolved starch particles—holds significant potential for animal feed, organic fertilizer, and biogas generation. However, its inherent high moisture content (typically 75–80%) poses critical challenges for downstream utilization. This article explores how advanced screw press dewatering technology addresses these hurdles, enabling consistent, cost-effective BSG valorization.

“Wastewater treatment plants are among the most energy-intensive industries. Electricity typically accounts for 70%–90% of total energy consumption, while aeration systems alone account for 50%–70%. Excessive aeration wastes electricity and disrupts process performance, while insufficient aeration increases the risk of non-compliant effluent and environmental penalties.”

Kitchen waste is one of the fastest-growing waste streams in commercial and industrial settings worldwide. Hotels, hospitals, food processing facilities, universities, and municipalities all face the same challenge: how to dispose of organic waste efficiently, compliantly, and at a manageable cost.

Effective organic waste management is a cornerstone of sustainable urban and rural development. For government agencies, public utilities, and community planners, the challenge lies not only in treating organic fractions—such as food waste, fruit and vegetable waste, garden and landscape waste, kitchen waste, and agricultural residues—but in doing so in a way that is economically viable, operationally efficient, and environmentally sound.
