CBM Drilling 5 Stage Solids Control System for India Drilling Company

October 11, 2026 — Tianjin, China

GN Separation, a leading global provider of drilling fluid processing and solids separation equipment, has announced the successful completion and factory acceptance testing of a fully customized 5-stage solids control system, purpose-built for a large-scale coalbed methane (CBM) development project operated by an international energy contractor. The milestone further solidifies the company’s position as one of the few suppliers worldwide capable of delivering fully integrated, application-specific mud conditioning solutions tailored to the unique operational challenges of CBM exploration.

Unlike standard 3- or 4-stage mud recycling systems designed for conventional oil and gas drilling, the new 5-stage system adopts a progressive separation architecture engineered specifically to address the well-documented complexities of CBM operations: high volumes of fine coal cuttings, reactive clays, entrained gas, and strict wellbore stability requirements in fragile coal seam formations. The full workflow combines high-G linear motion vibrating screen, a dedicated vacuum degasser, hydrocyclone desander, hydrocyclone desilter, and variable-frequency high-speed decanter centrifuge into one cohesive, skid-mounted package, delivering consistent removal performance for particles across the full 2 μm to 200 μm size range that dominates CBM drilling fluid streams.

According to the project engineering team, every core component of the system was designed, manufactured, and performance-verified in-house, ensuring full process compatibility and eliminating the performance mismatches that frequently occur when operators assemble multi-stage systems from mismatched third-party equipment. The system is certified to ATEX and CE standards, making it fully compliant with European and international hazardous area operation regulations, and features a modular layout that allows rapid on-site assembly without extensive custom fabrication work.

The company’s track record in CBM and unconventional gas development extends across multiple continents, with previously delivered systems now in active operation across India, Europe, Africa, and major domestic unconventional basins. 

GN 5-Deck Stack Vibrating Screen for Overseas Customer

GN Separation is proud to share the successful shipment of our self‑developed 5‑Deck Stack Vibrating Screen to an overseas mining client, bringing compact, high‑capacity wet‑screening performance for complex mineral‑processing conditions.

Many mineral‑processing sites face two common pain points: growing throughput demand and limited installation space. Traditional single‑deck vibrating screens require multiple units to finish multi‑stage particle classification, which occupies large floor space and pushes up capital investment. GN’s five‑deck stacked design solves this challenge by integrating five independent screening decks within one single machine frame. It greatly expands total screening area and boosts processing capacity without enlarging the overall footprint, perfectly matching projects with tight layout constraints.

 

Driven by the dual‑motor self‑synchronization system, the screen box generates stable linear motion for continuous, reliable operation under heavy‑duty working conditions. Optimized vibration control lowers power consumption and dynamic load, realizing energy‑saving production. High‑quality polyurethane screen panels are standard configuration. With outstanding wear‑resistance and elasticity, they effectively reduce material blinding and blockage during wet screening. Each deck can fit two or three screen panels for flexible aperture adjustment to satisfy varied separation targets. Thanks to pull‑bolt fastening structure, screen panel replacement and daily maintenance become quick and simple, cutting equipment downtime and operational costs for end users.
 
For overseas delivery, every unit goes through strict factory testing and heavy‑duty anti‑corrosion surface treatment. This robust build enables the machine to handle abrasive mine slurry, fine ore particles and mixed debris in harsh field environments. It performs well in wet classification, dewatering and solid‑liquid separation for mining, coal preparation and mineral tailings treatment.

 

This order once again proves GN’s capability to deliver customized screening solutions for global partners. Looking ahead, GN Separation will keep optimizing multi‑deck stack screen products and provide full‑range technical support, from pre‑sales technical communication to after‑sales guidance and spare‑parts supply, helping more overseas customers maximize production efficiency with reliable separation equipment.

Sludge Dewatering Screw Press Package for Overseas Client

News came that GN Separation has recently finished the fabrication for a new project for a client from overseas, it was a dewatering screw press combined with a chemical dosing unit. 

 

1.As a mature solution for solids-liquid separation, the combination of screw press and chemical dosing is widely adopted in sewage treatment plants, food processing factories, livestock breeding farms, pulp and paper mills, sludge disposal stations and industrial wastewater treatment workshops. The two pieces of equipment operate synergistically rather than independently, where the chemical dosing unit lays the foundation for efficient dewatering, and the screw press completes physical extrusion separation, greatly improving separation efficiency, reducing moisture content of solid residues and lowering overall operating costs.

2.Sludge dewatering in municipal wastewater treatment plants is the most mainstream application scenario. After sewage biochemical treatment, residual activated sludge exists in a colloidal state with rich bound water inside sludge flocs. Pure mechanical squeezing by a screw press cannot break colloidal structures to release bound water, resulting in high water content of dewatered sludge (over 85%) that fails to meet landfill, incineration or compost standards. In this case, the chemical dosing unit precisely configures and quantitatively adds flocculants including polyacrylamide (PAM), ferric chloride, polyaluminum chloride and lime emulsion into the sludge pipeline in advance. The dosing system is equipped with automatic dissolving tanks, metering pumps, mixing reactors and online concentration detectors, which can adjust the dosage of chemicals in real time according to sludge flow rate, solid content and pH value to avoid excessive chemical consumption or insufficient flocculation. 

3.After sufficient stirring and reaction, tiny sludge particles aggregate into large, dense and tough flocs that wrap free water and release bound water trapped inside colloids. The conditioned sludge is then transported into the screw press. Inside the screw press, the gradually narrowing screw cavity creates continuous mechanical extrusion pressure, filtrate flows out through filter screens, while solid sludge is pushed forward and discharged as dry sludge cakes. Cooperated with the chemical dosing unit, the water content of sludge discharged by the screw press can drop from more than 98% of original sludge to 60%–78%. Dry sludge cakes can be directly transported for incineration, land resource utilization or building material production, and separated filtrate flows back to the sewage treatment system for reprocessing, realizing closed-loop treatment of sludge.

 

With such scenarios, GN also make and provide other equipment located before and after the screw press and chemical dosing. For more information welcome to contact GN directly.
