About Us… J&R established in 1990 Over 20 years experience in the wastewater treatment market We began Piloting in Massachusetts with FAST and GEOFLOW

in 1998 at the Alternative Septic System Test Center First FAST single home installation in 1995; first GEOFLOW in

2000 Pioneers in the onsite market throughout New England Over 3,000 systems installed – primarily in Massachusetts and

Rhode Island We maintain greater than 80% of these installations through our

service division, Wastewater Treatment Services

Bio-Microbics Company

Overview

Founded in 1996 by Robert J. Rebori Over 47,000 installations in more than 60 countries Manufacture products for wastewater and storm water

industries Staff of engineers, biologists and chemists One of a very small number of treatment systems that have

a history of being able to treat high strength waste.

Nitrogen Reduction Every FAST system is designed and installed for

Nitrogen reduction Special built-in technology allows FAST wastewater

treatment systems to consistently reduce nitrogen levels by ~70%. Nitrogen reduction is a local issue in many locations and is a

major concern in all New England States.

Septic Tank Effluent vs. Treated Effluent Septic Tank effluent – typically 60 mg/L TN Treated Effluent after FAST - typically less than 19 mg/L in

residential

Membrane BioReactors (MBR)

Page 17: Case Study of a Shared Septic System

History of Membranes Membranes have been used for 100’s of years Manufactured membranes have been used in industrial

applications such as canning, dating back to more than 100 years ago.

In the 1960’s manufactured membranes were first utilized for drinking water purification.

With improvements in production methods in the 80’s and 90’s membranes were used in a broader spectrum of applications including Wastewater Treatment

Today, membranes are one of the primary technologies selected for Decentralized Wastewater Treatment

Why MBR?

The Highest, Consistent Effluent Quality BOD < 5 mg/L TSS < 2 mg/L Turbidity < 0.5 NTU Fecal coli form < 200 CFU/100 mL (without

disinfection) Significant nutrient removal capability Complete virus removal Reduction of pharmaceutical byproducts

Page 20: Case Study of a Shared Septic System

Why MBR?

Simple to operate (compared to other processes trying to achieve same effluent quality)

Robust biological process

Energy efficient

Ability to treat difficult wastewater

Why MBR?

Mixed Liquor Permeate

MLSS 5,000 – 16,000 mg/l

BOD < 5 mg/l TSS < 1 mg/l

Turbidity < 0.2 NTU

Benefits of Drip Systems Primary Characteristics

Shallow depth for application of

effluent. Uses most permeable

soil - aerobic zone. 6-10” below

grade.

Slow, uniform time dosing

prevents saturation of soil and

maximizes capillary action in soil.

Enhanced root growth improves

percolation.

Maximizes evapo-transpiration.

Practical Application of Benefits

Eliminates or reduces “mounds”

Cuts costs

Easy to install and maintain

Modified specifically for cold climates

Aesthetically pleasing

Conserve natural land contours and vegetation

Shared Systems using Onsite Treatment Over 100 residential shared systems in Massachusetts Utilizing onsite treatment allows for maximum use of

the site Allows for building on lots designated as Nitrogen sensitive Greater loading rates allowed = more bedrooms/homes to

build Flexibility of installation = maximization of site’s available

area One central treatment plant, disperse back to individual

lots, or to a central leach field FAST is a GreenSpec® listed product

Remedial General General Denitrification Provisional Piloting

GEOFLOW

General Remedial GEOFLOW is

recommended to be installed following an I/A approved treatment system Effluent quality must be

30/30 mg/L BOD/TSS

GEOFLOW Drip Offers Flexibility… Drip has been used in various applications from single homes to 1 mgd Soil “Quality” will determine amount of land required for the drip field The Drip Zones can be located wherever the GOOD soils are Zones can be a few hundred square feet to ¼ to 2 acres in size or larger No matter the size the same drip characteristics are maintained Can be used for more than residential flows…

Multi Home Subdivision – Harwich, MA

FAST and GEOFLOW installed June 2013 General Use Approval – local regulations

required a Nitrogen reducing treatment technology on the property.

Harwich requires all shared septic systems over 2,000 gpd to have a nitrogen reducing technology installed

However, no nitrogen testing is required for this site

Individual System Subdivsion– Seekonk, MA

80 Single Family Homes 28 FAST systems to be installed – approx. 22 to date Individual systems Proximity to a Seekonk watershed and conservation

lands required the use of denitrification treatment systems on 40% of the homes built.

FAST was chosen as a reliable, cost effective option Due to FAST’s performance history and the General

Use Denitrification Permit, the Seekonk BOH did not require nitrogen testing

Townhouse Development – Duxbury, MA

Installed in 2011/2012 Provisional Use Permit Site is located in a DEP Zone II designated

nitrogen sensitive area Using a FAST system allowed for:

550 gpd/acre – vs. 440 gpd acre with a traditional system – allowed for more bedrooms onsite

FAST is located below cul-de-sac/road – allowed for maximum utilization of space available

Condominium Delvelopment – West Yarmouth, MA

Seven FAST units installed starting in 2004 Each unit serves a building, which has multiple

condo units FAST was chosen for its denitrification ability as

well as its aesthetic value The site needed to maximize available space

while maintaining the use of its common areas FAST is located below grade with blowers and

vents at the back of the property
