# EZ Bersama (PT Empat Zekawan Bersama)

> EZ Bersama is an Indonesian specialty chemical and technical solutions company for the mining and industrial sectors, established in August 2026 in Jakarta. It supplies flocculants, coagulants, anti-scalants and activated carbon, and backs them with laboratory testwork, process engineering advice and on-site technical support. Tagline: "We Make Your Process EZ."

Focus areas: mineral processing, solid-liquid separation, water treatment and process optimization.

How EZ Bersama works: (1) Understand - learn the customer's process, feed material and operating targets, on site or from samples; (2) Test - lab-scale testwork to select the right flocculant, coagulant or specialty chemical; (3) Implement - practical guidance on process flow and chemical injection, with on-site support; (4) Optimize - track results and fine-tune dosing and operation to improve cost and performance.

## Product application & services

- [Thickeners & Solid-Liquid Separation](https://www.ezbersama.com/thickeners.html): EZ FLOC flocculants (A311, A5508, A5672-T hybrid with ATBS, A6XX-series ATBS) and EZ CLEAR coagulants (456 and 775 liquid-organic; 478 and 479 inorganic) for higher underflow % solids, desired overflow clarity and controlled rheology in thickeners, CCDs and clarifiers.
- [Geotube & Dredging Dewatering](https://www.ezbersama.com/geotube-dewatering.html): flocculant and coagulant selection plus advice on process flow, chemical injection and slurry-chemical interaction. Target: desired cake SG inside the geotube (and after relaxation), compliant released-water clarity, within budget. Products: EZ FLOC A311, A5508; EZ CLEAR 456, 775, 478, 479.
- [Antiscalant: Scale Prevention](https://www.ezbersama.com/antiscalant.html): EZ AS series (EZ AS 1000, EZ AS 4000 and 4000A) prevent calcite, gypsum, barium sulfate and other scale at temperatures up to 200 °C, moving plants from a pipe/pump replacement strategy to a maintenance strategy.
- [Activated Carbon for Gold Mining](https://www.ezbersama.com/activated-carbon.html): EZ CARB series (EZ CARB 1000, 1100) made from Indonesian coconut shell, steam-activated, high hardness and low ash. On-site testwork: EZ CARB 1000 reached a peak gold loading of 2,010 g/t versus 1,750 g/t for a competitor carbon (+15%).
- [Run-off Mine Water Management](https://www.ezbersama.com/run-off-water.html): EZ CLEAR 456 and 775 liquid coagulants and EZ FLOC A5208 and A5508 powder anionic flocculants. On-site testwork reduced chromium from 783 to 17 ppb (97.8%), TSS from 524 to 33 mg/L (93.7%) and turbidity from 607 to 63 NTU (89.6%).
- [Settler & Washer in the Bayer Process](https://www.ezbersama.com/bayer-process.html): EZ X-SERIES hydroxamate flocculant EZ X6400 for settler and washer applications in alumina production, giving very low solids in overflow under strongly caustic, high-temperature conditions.
