  • About CHEM.ENGI

     

    Not just a chemical supplier

    CHEM.ENGI are chemists and engineers.

    We not only develop and supply chemical products for wastewater treatment and sludge dewatering, but also provide engineering support that is necessary for optimal use of the chemicals.

    We produce, distribute, and "install" chemical products for you.

    Sustainability is our goal

    Our aim is to help you treat your wastewater and sludge economically in one of the most environmentally friendly ways. We supply organic biodegradable flocculants for solid-liquid separation. Even GRAS approved products. We would like to stop the negative spiral of waste creating another waste treatment!

    Based on more than 40 years of experience

    We are group of people who are committed to solving your problems, not just supplying chemicals. We have been in wastewater and waste management industry for more than 40 years and that is long enough to understand that customer orientation is the only reason for our existence.

     

    CHEM.ENGI is a joint venture of Japanese and British companies who have been in water treatment business for decades. After the successful project for the Europe's largest distillery's bio energy plant, we decided to form CHEM.ENGI to spread our solution to the world together.

    Aqueous dispersion polymer flocculant

    We believe it is possible to have

    EFFECTIVE, ORGANIC and yet AFFORDABLE

    polymer flocculant that doesn't pollute and cost the earth.

     

     

    Yes, it is organic.

    Yes, it is biodegradable.

    Yes, it is non-toxic.*

    Yes, it is low-dosage.

    Yes, it works.

    YESfloc®

     

    See how different YESfloc® is...

    • Biodegradable, non-toxic*, flocculant derived from natural sources.
    • GRAS approved product
    • Low dosage 
    • High dewaterability 
    • Easy handling, no maturation time, works instantly 
    • Dilution water saving by more than 10 times
    • Eco-friendly manufacturing process, free from surfactants and solvents  

    You should get YESfloc® if you want to...

    • Dewater and recover solids from distillery or brewery wastes and turn it into animal feed.
    • Dewater algae from a lake and return the filtrate straight back to the lake. 
    • Dewater lagoon sludge and return the filtrate straight back to the lagoon.
    • Dewater digestates well and yet minimize polymer consumption.
    • Dewater waste activated sludge and return the solids to the field without environment impact of the polymer.  
    • Dewater raw wastewater directly and remove not only suspended solids, but also fat and grease.
    • and even more! 

     

    The products can be supplied in 25kg tub or IBC tank.

    The production of YESfloc® adheres to ISO9001 and ISO14001.

    We also have oil based emulsion and granular flocculants and coagulants for standard wastewater and sludge applications.

    *Toxicity based on acrylamide content defined by GRAS standard. Not all products of YESfloc® are non-toxic.

  • Case Studies

     

     

     

    Contribution to the ambition of Europe’s largest alcoholic drink distillery to be environmentally sustainable.

    Dewatering raw spent wash

    The Europe’s largest alcohol drink distillery located in Scotland has a great ambition to be the world’s most environmentally sustainable distillery. Their bioenergy plant generates renewable energy from spent wash (mixture of wheat, malted barley, yeast and water produced during distillation). The spent wash needs
    to be separated into water and the solids, but the polymer flocculant that is necessary to be used for separation can be a massive operational cost if it is not optimized well. We, however, managed to optimize the whole process from analysis of the spent wash, conditioning, flocculating, and to dewatering for the customer. After our chemical and process optimization, the bioenergy plant has been receiving quality dry spent wash as renewable biofuel. And the polymer flocculant used is of course biodegradable eco-friendly product.

    Flocculating raw wastewater from pastry factory

    Primary treatment of wastewater

    The factory was expanding its production and their wastewater started breaking the discharge consent. We engineered a complete package of primary wastewater treatment using YESfloc® and AMCON's VOLUTE dewatering screw press, which had been working to reduce suspended solids by 85%, fat and oil by 95%, and COD by 87%.

    Turning spent wash digestate to animal feed

    One of the biggest Scottish whisky distilleries

    Due to the nature of spent wash, it is not easy to flocculate suspended solids in spent wash. Moreover, the distillery wanted to recycle dewatered digestate spent wash as animal feed. YESfloc® with its water based GRAS approved spec was finally the only flocculant that met these criteria and we managed to engineer a transformation of spent wash digestate to animal feed.
