Illinois; Rainwater Harvesting Filter

1. RAINWATER HARVESTING FILTER
INTRODUCTION: MIFAB continues its leadership role in rainwater solutions
with the introduction of a rainwater harvesting filtration
system. The ready availability of high quality water is
something that we have taken for granted for a long time.
Increased urbanization, changing weather patterns and
both the environmental and financial cost of water provision
now require us to look harder at how we utilize our natural
resources.
The large roof areas typically found in commercial construction provide an ideal opportunity to collect
significant volumes of rainwater that are usually considered to be a waste product. By utilizing the MIFAB
Rainwater Harvesting Filter in conjunction with traditional or siphonic roof drainage, much of this water
can be harvested, filtered and stored. The filter can be sited inside or outside of the building and may be
positioned at high level, low level or underground offering the most flexible system on the market. The
MIFAB system provides highly effective filtration across a wide range of flow rates removing all solids and
particulates above 400μm as well as providing a barrier to mosquitos and other insect life.
The removal of solid and organic matter from the collected rainwater prevents deoxygenation during storage,
ensuring that water remains fresh. The filter is designed to be self-cleaning requiring only minimal, simple
maintenance. The modular design simplifies the integration of water harvesting into bigger projects whilst
stainless steel construction provides robust, durable components ideally suited for the rigors of commercial
and industrial environments. The naturally soft water collected is suitable for toilet flushing, laundries,
vehicle wash, irrigation, fire protection and other non-potable uses.

2. How the system works
The MIFAB Rainwater Harvesting Filter
is designed to efficiently capture and Diffuser plate
filter rainwater from the roofs of Rainwater inlet
commercial buildings. For large roof
areas, multiple filtration systems may
be installed in appropriate locations
or increased capacity systems may be
used. Our modular design provides the
opportunity to utilize longer or deeper
filters, depending on where it is intended
to install the system maximizing the
volume of water captured. All MIFAB
filters are manufactured in the USA
from the highest quality components.
In view of the diverse climatic Filtration
conditions we face in the USA, MIFAB screen
offer the local architect, engineer
and contractor the option of selecting
storage vessels from local providers.
