Simply put, recycling water in stone and granite shops is our wheelhouse. It’s how we got started in the business many years ago and we just keep getting better. With hundreds of systems still running virtually trouble free after years of service, we’re confident that we can find a solution for your stone and granite fabricating business. In addition to gaining a competitive edge by positioning yourself as an environmentally friendly company, recycling your water can save you hefty fines for non-compliance of city, state, and federal regulations. There is also a tremendous cost savings on your decreased use in municipal water.
Where do we start?
We like to get involved as early on in the process as possible. If you have an existing operation, or are just setting yourself up for stone fabrication we can help make the transition go as smoothly and efficiently as possible. No matter where you are in your process though, we want to help. Because we do this every day, there will likely be some questions we will ask, or suggestions we will have that you might not have considered. Part of the cost effectiveness of our solutions lies in the planning phase by making sure we have a complete understanding of your needs.
Most of our solutions include one or more of these components:
- Rapid Settlement Systems use inclined plate clarifier technology to treat the water with minimal ongoing maintenance.
- Filter Presses produce very clean water and dry sludge cakes. They do require more ongoing maintenance than our RSS Systems.
- Slurry Silo products are effective in a variety of settings. They are used to treat water prior to city drain, and for complete water reuse.

Settling of stone, granite, and glass water requires space and time. Each particle has a rate of settling – the farther the particle needs to settle the longer it takes to settle. Larger particles settle faster than smaller particles. Stone, granite, and glass industry water efficiency and rates of settling can be increased by injecting polymers (products/chemical treatment) into the waste stream which increase the size of the particles by attracting and bonding the individual particles together. Settling efficiency can also be increased by adjusting fluid dynamics of the water and by increasing settling surface area and settling time. Settling Ponds, Silos (Products/RS Tower), lamella clarifier, inclined plate clarifier and Rapid Settlement Systems (products/RSS) utilize settling.
Filtration systems for stone, granite, and glass water requires a physical barrier that will not allow particles of a certain size to pass through. Particle size is measured in microns. The human eye can see down to approximately 50 micron. Suspended solids in water typically are measured down to .1 micron and up to about 150 microns. Filters are rated down to a certain size – that is they can filter out everything larger but not smaller than a certain micron rating. Filter barriers can be filter cloth, a membrane, a bed of sand, a filter module, or a variety of other medias. The most common industrial wastewater filtration systems are typically plate and frame press, filter press (Product/RS Press), or rotary vacuum drum filter (product/rotary vac drum) equipment. Pressure drops from 1 side of the barrier to the next indicate when the filter load has been maxed out and cleaning or replacing needs to take place.
