THE PROCESS


KINGSPAN KLARGESTER

POPULATION (P): NUMBER OF PEOPLE THE SYSTEM WILL SERVE.

POPULATION EQUIVALENT (PE): COMMERCIAL LOADING SHOWN

AS DOMESTIC EQUIVALENT

BIOCHEMICAL OXYGEN DEMAND (BOD5): MASS CONCENTRATION

OF DISSOLVED OXYGEN CONSUMED UNDER SPECIFIED

CONDITIONS (5 DAYS AT 20°C WITH NITRIFICATION INHIBITION) BY

THE BIOLOGICAL OXIDATION OF ORGANIC AND/OR INORGANIC

MATTER IN WATER.

AMMONIA EXPRESSED AS mg/l N: AMMONIA IS NH3, AMMONIUM IS

NH4OH. IN WASTEWATER WE FREQUENTLY REFER TO AND USE

AMMONIA/NH3. THE TERM AMMONIA USUALLY INCLUDES AMMONIUM

AS WELL.

SUSPENDED SOLIDS (SS): SMALL SOLID PARTICLES WHICH REMAIN

IN SUSPENSION IN WATER. USED AS ONE INDICATOR OF WATER

TYPICALLY FOR WASTEWATER APPLICATIONS. THE AMOUNT OF

SUSPENDED SOLIDS INDICATES HOW CLOUDY THE WATER IS.

KINGSPAN KLARGESTER

ACTIVATED SLUDGE SYSTEMS

THE PROCESS INVOLVES AIR BEING INTRODUCED INTO A MIXTURE OF

SCREENED AND PRIMARY SETTLED SEWAGE TO DEVELOP A BIOLOGICAL

FLOC WHICH REDUCES THE ORGANIC CONTENT OF THE SEWAGE.

(INCLUDING EXTENDED AERATION SYSTEMS)


KINGSPAN KLARGESTER

BIOLOGICAL / SUBMERGED AERATED

FILTER (BAF / SAF) SYSTEMS

BIOLOGICAL AERATED FILTER COMBINES FILTRATION

WITH BIOLOGICAL CARBON REDUCTION


KINGSPAN KLARGESTER

ROTATING BIOLOGICAL

CONTACTOR (RBC) SYSTEMS

ROTATING BIOLOGICAL CONTACTORS ARE MECHANICAL SECONDARY TREATMENT

SYSTEMS. DISCS SUPPORT THE GROWTH OF BACTERIA AND MICRO-ORGANISMS

TO BREAK DOWN AND STABILISE ORGANIC POLLUTANTS.


KINGSPAN KLARGESTER

SEQUENTIAL BATCH REACTOR

(SBR) SYSTEMS

A SIMILAR PROCESS TO ACTIVATED SLUDGE, SBR SYSTEMS CONSIST OF A FIVE

STAGE PROCESS – SCREENED FILL, REACT, SETTLE, EMPTY / RECYCLE, REST.


KINGSPAN KLARGESTER

PEAT FILTER MEDIA SYSTEMS

SETTLED LIQUID FROM PRIMARY TANK IS PUMPED TO AND

FILTERED THROUGH AN ORGANIC MEDIA (PEAT).

CONNECT TO MAINS BY PUMPING

SELECTION OF THE CORRECT PUMP STATION IS CRITICAL

PUMPING STATIONS SHOULD HAVE 24 HOURS STORAGE IN THE

CHAMBER (IN CASE OF BREAKDOWN

OR POWER FAILURE).

WHAT DOES THE SPECIFIER NEED TO KNOW?

- VOLUME OF WASTE

- TYPE OF WASTE (SEWAGE, EFFLUENT, SURFACE WATER

- DISTANCE TO BE PUMPED

- TOTAL HEIGHT TO BE PUMPED

- INLET DEPTH OF SEWER TO CHAMBER

- DIAMETER OF RISING MAIN

- POWER SUPPLY AVAILABLE

REGULATIONS & CODES OF PRACTICE

SR66 PROVIDES GUIDANCE ON THE SELECTION OF WASTEWATER

TRATMENT PLANTS FOR USE IN IRELAND

IT PROVIDES GUIDANCE ON THE MINIMUM PERFORMANCE REQUIRED ON

UNITS TESTED TO I.S. EN 12566 (parts 1,3,4 AND 6)

IT PROVIDES GUIDANCE ON THE SCALING AND SLUDGE CAPACITY.

ALL TEST CERT’S MUST SHOW THE FOLLOWING RESULTS.

WATERTIGHTNESS – PASS/FAIL

STRUCTURAL BEHAVIOUR - PASS/FAIL

DURABILITY - PASS/FAIL

SEPTIC TANK – TREATMENT EFFICIENCY >99.5%

SEPTIC TANK – SLUDGE VOLUME as per min requirements EPA CoP

TREATMENT PLANT – PART 3 & 6 MUST STATE THE NUMBER OF

DESLUDGES DURING THE TEST PERIOD.

ELECTRIC POWER CONSUMPTION declared kWh/day

PERFORMANCE. 20mg/l BOD, 30mg/l SS. 20mg/l NH4-N

BUILDING REGULATIONS 2010 PART “H” + SR66-2014 REQUIRE THE FOLLOWING.

EPA CoP 2009 WASTEWATER TREATMENT AND

DISPOSAL SYSTEMS FOR SINGLE HOUSES. (PE<10).

ALL SITES NOT ABLE TO CONNECT TO THE MAINS WATER NETWORK

MUST COMPLY WITH THE ABOVE CODE OF PRACTICE.

ENSURING THAT THE WASTEWATER IS DEALT WITH AND DOES NOT

CAUSE A HEALTH RISK

EACH SITE AS PART OF PLANNING SHOULD HAVE A SITE ASSESSMENT

CARRIED OUT BY A PROFESSIONAL SITE ASSESSOR. (FETAC CERTIFIED

OR EQUIVALENT)

ALL SYSTEMS TO BE INSTALLED MUST COMPLY WITH PREFORMANCE

STANDARDS I.S. EN12566 PARTS 1-7

IN ADDITION TO I.S. EN12566 THE UNITS MUST MEET THE STANDARD

SITE ASSESSMENT.

THIS IS REQUIRED TO DETERMINE IF A SITE IS SUITABLE FOR AN ON-SITE

WASTEWATER SYSTEM.

TESTING OF THE GROUND SHOULD BE DONE IN ACCORDANCE WITH EPA

CoP. 2009:

A COMMENCEMENT NOTICE WILL ONLY BE GIVEN ONCE A FULL REPORT

HAS BEEN PRESENTED AND APPROVED BY THE LOCAL PLANNING

OFFICE.

THREE FACTORS SHOULD BE CONSIDERED

ARE THERE ANY RESTRICTIONS RELATING TO THE SITE?

IS THE SITE SUITABLE TO TREAT THE WASTEWATER? (attenuation)

IS THE SITE ABLE TO DISPOSE OF THE WASTEWATER VOLUMES?

(hydraulic load)
